exclude bright sun-light and to keep the rain from beating in and the screens excluding insects. The invention has for its object to provide an extensible or adjustable blind which may be made wider or narrower, so that it will be adapted to be fitted into windows of difi'erent widths. and with such extensible or adjustable blind is preferably combined an extensible or adjustable screen; as also to provide such a construction of an extensible blind, or of a combined extensible blind and screen, as will prevent rain from beating in around the same. To this end the blind is made in two sections each carrying what may be termed half slats, one series of which are provided with turned-over edges, for any desired parts of their lengths, these turned-over edges providing a series of guides in which the other series of half slats fit in such a manner that the blind-may be made wider or narrower as may be desired. The side pieces of the blind, which may be either wood or metal, are preferably provided with metallic strips or guides adapted to receive an extensible screen and hold the same in such a manner that it may be slid up and down, if desired, relative to the blind, the screen being made in two parts so astobe extensible or adjustable with the blind, in being fitted into a window of any particula 1' width. The frame of the blind is of such constri'iction that it may be securely held in place by the lower window sash beneath whichit is inserted when the sash is raised. lathe accompanying drawings, Figure .1 a vertical section showing a combined blind and screen in position in a window frame, and Fig. 2 is a horizontal sect-ion of the same.

frame. Fig. 5 is a detail View to show the fastenin means for securing the two parts of the adjustableiblind together.

Referring to the drawings, 12 denotes, a window frame of any suitable or wellknown construction; 13 denotes the lower sash,"in raised or elevated position, and 14 denotes the upper sash. The blind comprises two side pieces 15 to which are at.-

tached, in any suitable manner, the half slats 16, which are preferably of sheet metal. Each of the half slats of one series is preferably provided with turned-over edges 17 forming a guide receiving the opposite or companion half slat which 1s loosely embraced by said guide so that the side pieces of the blind may be moved nearer to or farther from each other with the half slats carried by one side piece sliding freely in the said guides formed on the opposite half slats, the half slats thus overlappingeach other so as to afford n-actically contlnuous slats in such a manner as will prevent rain from coming in at the window at the joints between the half slats.

Any suitable means may be employed for securing the adjustable or extensible blind in any desired position, such means, as herein shown, consisting of a suitable clamping bolt 18 mounted in one of the half slats and received in a slot 19 in the opposite half slat, such slot permittinv lateral adjustment or extension of the blin which, after being adjusted to the proper width, may have its two parts fastened together by means of a nut 20 with which the said clamping bolt is provided. Any desired number of clamping bolts may be provided, although one or two for each blind will probably be all that will be necessary, for practical use.

The side pieces 15 of the blind are provided with vertical metallic strips 21 the. outer edges of which will preferably overlap" the insides of the side strips of the window frame, and the inner edges of said metallic strips 21 are bent down to receive flanges 22 at the outer sides of the two-part adjustable screen 23, so that the said screen may be raised or lowered relative-to the blind in the'guides provided by the said strips 21. As will be seen, the inner edges of the strips 21 overlap the flanges 22, thereby maintainingthe parts of the screen in engagement with or in proper position with respect to the side pieces of the blind as thelatter are moved inwardly and outwardly for pnrmanner, as by soldering or by folding over thin sheet metal in such a manner as to embrace the wire netting. One .part or member of the adjustable screen is preferably provided at its top with a lip 24 and at its bottom with a similar lip 25, said lips forming grooved guides loosely overlapping the other screen member so that said members may be adjusted laterally relative to each other to form an adjustable or extensible screen which follows, in its ad'- justing or extending or collapsing movements, the extensible or adjustable blind on which it is mounted.

The side. pieces 15 of the blind are preferably provided at their tops with notches 2t to receive the lower sash 3 which is let down into said notches after the blind has been inserted in place in the window frame, thereby locking the blind at its top beneath the window sash so as to hold it in place. The said side pieces of the blind are also preferably provided at their bottoms with notches 28 which fit against the window sill or the lower strip of the window frame in such a manner as to steady the bottom part of the combined blind and screen on the window frame.

To prevent rain from beating in beneath the raised lower sash 13, at the top of the blind, the upper half slats are provided with extensions or guard strips 29 which may be integral therewith or attached thereto in any suitable manner and arranged to overlap the bottom of the raised lower sash 13; while the vertical metallic strips 21 at the sides of the blind, and which overlap strips on the window frame, will prevent rain from beating in at the sides of the device.

The strips 21, it will be seen, perform the double function of excluding rain and of assisting in maintaining the blind in position, it being obvious that said blind will be prevented from falling inwardly partly by the notches 26 which engage the upper window sash and partly by the notches 28,

engaging the sill, while it will be prevented from falling outwardly partly by the notches 26 and partly by the strips 21, saidstrips preventing the blind from slipping outwardly at the bottom.

To prevent the screen from slipping down out of the blind in the guideways in which it slides up and down freely, when the blind is out of the window, the blind -is preferably provided with a stop consisting, as herein shown, of a strip 30, which is overlapped by lips 24 and 31 on the members of the extensible blind.

\Vhile it is preferred to use the extensible blind in combination with an extensible screen it will be understood that. the extensible blind might be made and sold separately, or without the extensible screen, without departing from the essence of the invention itself, as the blind itself, without the screen, might be useful in many instances. It will also be understood that the invention is not to be limited to the details herein shown and described, but may be varied, within the province of mechanical skill, without departing from the essence thereof.

Having thus described my invention I claim and desire to secure by Letters Patent:

1. An extensible or adjustable bl nd, comprising two side pieces connected by slats of adjustable length, combined with a screen mounted on said blind for movement relative thereto.

4. The combination with an extensible or laterally adjustable blind, of an extensible or laterally adjustable screen provided with flanged edges, the frame of the blind provided with vertical uideways overlapping the flanged edges of said screen, whereby said screen may be raised or lowered relative to the said blind but will be maintained in engagement therewith.

5. An extensible blind comprising two side pieces, each of which is provided with a series of half slats, one series of said half slats being furnished with guides in which the other series of half slats loosely fit, so that said half slats overlap, combined with a laterally adjustable screen fitted to and held in place on the side pieces of the said blind. V
